Since Mup uses a simple text file as input rather than a GUI,
it can be used very successfully by people who are blind,
to produce professional-quality music output.
If you can edit a text file, you can create Mup input.

Additional features that make Mup more accessible for blind users than
most other music publication programs include:

Mup can produce
MIDI output,
so you can "proofread&quot your input
by listening to it.

Mup handles all the layout details automatically, so while you might sometimes
wish to briefly enlist the help of a sighted friend just to ensure the
final product looks as nearly "perfect" as possible,
in most cases, the output will be very acceptable without any extra fiddling.

The
Mup User's Guide
is available in HTML format, and since it is straightforward
HTML without lots of extraneous formatting tags,
almost any text-to-speech or text-to-Braille software should be able to
handle it easily.
